What is the main function of any organism's reproductive system?
the reproductive system has four functions: To produce egg and sperm cells. To transport and sustain these cells. To nurture the developing offspring.
It haves four functions.... to produce egg and sperm cells, to transport and sustain these cells :(:
Which changes occur in the composition of the earth's layers from the core to the surface?A. The material is hotter and denser.
B. The material is cooler and denser.
C. The material is hotter and less dense.
D. The material is cooler and less dense.
The correct answer would be B. The material is cooler and denser.
As we move from the core to the crust of the earth, the temperature and pressure of the layer keep on decreasing.
For example, the temperature of the inner core is around 9000 to 13000° Fahrenheit. The temperature of the outer core is around 7200 to 9000° Fahrenheit.
Similarly, the pressure also decreases as we move from core to crust.
Consequently, the density of the material increases as they become solidified.
B, the material is cooler and denser
Suppose that in a lab you could remove all the oxygen from the terrarium. What would happen to the plants? Why?
They would still thrive. Plants only require sunlight and water to produce oxygen and glucose. The plant would just increase the concentration of oxygen in the terrarium over time.
Science 6. Grade 6.Can anyone please help me answer these Science 6 questions Grade 6. Right away soon as possible?
Question 1 Match the description of the different kinds of symbiosis with its type. Choices are commenalism , mutualism, parasitism
In this type of symbiosis, one organism is helped while the other is harmed.
In this type of symbiosis, both organisms benefit.
In this type of symbiosis, one organism benefits while the other is neither helped nor harmed.
Question 2 Fleas and ticks get their food by sucking the blood of a dog or cat that they are attached to. This can transmit diseases and harm the dog or cat. This is an example of which type which type of symbiotic relationship?
Question 3 The yucca moth takes pollen from one yucca plant to another plant, which helps pollination and fertilization. While the moth is there, it lays it eggs in the plant. When the eggs turn to larvae, they eat some of the plants seeds, which doesn't harm the plant. This is an example of which type of symbiotic relationship?
Question 4 Athlete's foot is a type of fungus that grows on human's feet. It is irritating and can be painful. This is an example of which type of symbiotic relationship? .
Question 5 In the ocean, barnacles attach themselves to the belly of many whales. The barnacles are getting a place to live but the whale is usually not affected at all. This is an example of which type of symbiotic relationship?
Question 6 You're on vacation at the shore and get bit by a mosquito at night while walking the boardwalk. The mosquito feeds off of you when it bites you and you are left with a painful, itchy, swollen red mark on your skin. This is an example of which type of symbiotic relationship?
Question 7 Alligators will usually not eat certain species of birds. They will actually open their mouths and let the birds perch on their jaws. When this happens, the bird picks at the food particles in the alligator's teeth getting food. The alligator allows the birds to do this because it gets its teeth cleaned. This is an example of which type of symbiotic relationship?
Question 8 ""Good for you, bad for me," is a saying that would describe which type of symbiotic relationship?
Question 9 "Good for me, doesn't bother you,"is a saying that would describe which type of symbiotic relationship?
Question 10 "Good for me, good for you,"is a saying that would describe which type of symbiotic relationship?
1. A) parasitism B) mutualism C) commensalism
The symbiotic relationships are classified as parasitism (one organism benefits while the other is harmed), mutualism (both organisms benefit), and commensalism (one organism benefits while the other is neither helped nor harmed). The examples given illustrate these types of symbiotic relationships in various life forms.
Answer for questions 1-3: The type of symbiosis where one organism is helped while the other is harmed is parasitism. When both organisms benefit it is termed mutualism. When one organism benefits and the other is neither helped nor harmed it is commensalism.
Answer for question 4: Fleas and ticks sucking blood and potentially harming dogs or cats is an example of parasitism.
Answer for question 5: The yucca moth and yucca plant relationship exemplifies mutualism, as the larvae get food and the yucca plant gets pollinated.
Answer for question 6: Athlete's foot fungus thriving on a human causes harm to the host and signifies parasitism.
Answer for question 7: Barnacles living on whales without causing them harm is a case of commensalism.
Answer for question 8: Mosquitoes feeding off humans by biting is another example of parasitism.
Answer for question 9: Birds cleaning alligators' teeth without harm and gaining food is a type of mutualism.
Answer for question 10: When one organism benefits at the expense of another, as in 'Good for you, bad for me,' it reflects parasitism. 'Good for me, doesn't bother you,' aligns with commensalism since one species benefits and the other remains unaffected. 'Good for me, good for you,' typifies mutualism, where both species benefit.
PLEASE HELPIn a particular type of cat, coat color follows the dominant/recessive pattern of inheritance. The allele for a brown coat (B) is dominant to the allele for a white coat (b).
A cross between two white-coated cats would result in A. white-coated kittens or brown-coated kittens. B. white-coated kittens with brown spots. C. white-coated kittens only. D. brown-coated kittens only.
A cross between two white-coated cats would result in white-coated kittens only. Thus, the correct option for this question is C.
What is Inheritance?
Inheritance may be defined as a process through which characters are transferred from one generation to the next generation. It is also known as heredity. It builds the base for genetics and genetic cross.
According to the context of this question, the allele for a brown coat (B) is dominant to the allele for a white coat (b), i.e. B > b. Now, if a white coat (bb) is crossed with a white coat (bb), it never produces a brown-coat kitten. It is because B is required in order to express dominant traits in progenies.
Therefore, a cross between two white-coated cats would result in white-coated kittens only. Thus, the correct option for this question is C.
